ICL3241CB

Overview

The ICL3241CB is a triple line transceiver manufactured by Harris Corporation, designed for EIA-232 and TIA-232 communication standards. It features three drivers and three receivers within a single package. The device utilizes Schmitt trigger inputs to provide noise immunity. It operates within a temperature range of 0°C to 70°C and is housed in a 28-pin Plastic Dual Small Outline (PDSO) or SSOP package. The component supports a maximum output swing of 10 V and includes an output low current capability of 1.6 mA.

Feature Summary

• Triple driver and receiver configuration for simultaneous serial data transmission and reception
• Schmitt trigger input characteristics for enhanced noise filtering
• Compliance with EIA-232 and TIA-232 interface standards

Applications

• RS-232 serial communication interfaces
• Modem connections
• Industrial control systems requiring serial data transfer

Procurement Notes

Verify the manufacturer designation carefully, as Intersil acquired Harris Semiconductor assets. Confirm the specific suffix 'CB' corresponds to the required plastic SSOP/PDSO-28 package variant. Ensure RoHS compliance status matches project requirements, noting that older Harris-branded components may differ from current Intersil/Renesas production runs.

Selection Notes

Select this component when a triple channel RS-232 solution is required without external charge pumps. Verify that the 0°C to 70°C commercial temperature range meets environmental specifications. Compare pin compatibility with other triple transceivers if space constraints require alternative packages.

Part Context

This part belongs to the ICL324x series of line transceivers. It shares functional similarities with the ICL3241 but differs in packaging and specific thermal ratings. The component represents legacy technology from Harris Semiconductor, now maintained under Intersil and Renesas product lines.

Replacement Considerations

Check for equivalents such as the MAX3241 or TRS3241. Verify pinout compatibility before substitution. Note that newer generations may offer improved ESD protection or lower power consumption.
